Officers were doing a routine patrol when a detective spotted Mailhot. They arrested her without incident. She now faces felony theft and drug possession charges.

Earlier, Manchester police said an 84-year-old woman was picking up groceries with her husband at Stop and Shop on Lincoln Street on April 21 when a woman reached into her cart and grabbed her purse.

A surveillance camera caught the thief shoving the purse up her shirt before leaving the store, police said.

"The suspect victimized an elderly woman in the presence of a 4- or 5-year-old child," said Manchester Police Capt. Nick Willard. "(The woman took) the purse from the elderly woman's shopping cart while she was in the produce section. (She) put it underneath her shirt and (left) the store."

Police said the victim didn't realize her purse had been stolen at first, thinking she had left the purse in the bathroom. When she learned of the theft, police said the woman was devastated that someone had stolen the cash she planned to use for groceries.

Police said they wanted to find the woman because they fear other victims could be out there.
